Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1968. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property was initially developed in 1968 as an industrial painting facility and warehouse, operating as M & M Finishers through 2007. Metal finishing and painting operations involved dip tanks, paint application and curing, on-site use and recycling of solvents including trichloroethylene (TCE), and on-site evaporation of dip tank liquids; cadmium contamination has been attributed to those historical activities. Remediation has included an underground storage tank removal in 1993, and the site remains enrolled in the Voluntary Cleanup Program with quarterly groundwater monitoring — including drumming of contaminated purge water — continuing through at least 2025. That history could support an insurance cost recovery claim against carriers who issued insurance policies 40+ years ago.

Why Historical Insurance Policies May Be Accessible

Pre-1986 Commercial General Liability (CGL) policies were occurrence-based and did not contain an effective pollution exclusion in Washington. If contamination occurred while those policies were active, those historical insurance carriers may still have a legal obligation to fund the cleanup costs, even if the business closed or the property changed hands.

Metal finishing and solvent operations at this property began in 1968, placing the originating contamination squarely in the era of occurrence-based Commercial General Liability policies that carried no effective pollution exclusion in Washington. TCE and cadmium releases from industrial dip tanks and painting processes are precisely the kind of slow, cumulative discharges those pre-1986 policies were written to address. The documented remediation trail — a UST removal, decades of quarterly groundwater monitoring, and continuing VCP oversight through at least 2025 — represents expenditures tied directly to operations that pre-1986 carriers insured, making historical policy recovery a viable avenue for costs already incurred and those still to come.

Restorical's role is to locate viable historical policies, determine whether a successful coverage claim is possible, and assist our clients and their legal counsel to obtain insurance coverage. Restorical then manages the claim, including accounting, to ensure the cleanup is funded in a timely manner.

The Restorical Proven Process

Task 1 — Research and Analysis
Restorical searches for viable historical insurance policies, researches the site history, analyzes the contamination impacts, and underwrites potential coverage — including a proprietary trigger analysis. At the end of Task 1, we provide a clear yes or no on whether a successful cost recovery is possible, along with a strategy and recommendation specific to your situation, even if you are not the policyholder.
Task 2 — Coverage and Funding
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim, negotiate and secure insurance coverage. Restorical will manage the ongoing claim process, including accounting to ensure the insurance companies are funding your remediation in a timely manner.
